実験手順

CH2═C(CF2OSO2F)2 is added gradually to FSO2CF2CF2OK, which is prepared from freshly dried KF (3.9 g, 0.067 mole) and FSO2CF2COF (12 g, 0.067 mole) in dry diglyme (30 ml). The resulting mixture is stirred 3 hours at 20° C. The reaction mixture is poured into water. The organic layer is washed with aqueous sodium bicarbonate, then water, and then dried over MgSO4. Distillation gives CH2═C(CF3)CF2OSO2F (0.5 g) and CH2═C(CF2OCF2CF2SO2F)2 (9 g, 58% yield, b.pt. 95-96° C. at 15 mm Hg).
